WHEELED PLOW. I

Application filed June 30. 1911.

To all whom. it may concern Be it known that I, ALnxUs C. Lrxnennx, a citizen of the l nited States, residing at Moline. in the county of Rock Island and State of Illinois, have invented certain new useful Improvements in lvheeled plows, of which the following is a specification, reference being had therein to the arrompanying drawing.

This invention relates to wheeled plow-s and has referuive more particularly to the means for adjusting the supporting wheels up and down in order to raise and lower th. plow.

In accordance with my invention the frame of the plow is supported on opposite sides by ground wheels. one a land wheel and the other a iurrow wheel, which wheels are movable up and down with reference to the frame. i'lldjusting levers are operatively connected with the respective wheels in such manner that they may be adjusted independently of each other, and means are proizled whereby the levers are adapted to cooperate with ,each other so that by the op- "ration of one of the levers both wheels may .-i"t-o .*n in the accompanying drawings to illustra e by way of example the application of my unprovml adjusting" mechanism. oomprises a number of fore and aft beams 1, 2, 3, etc. equipped with suitable mold board ph s and wnnected at their front ends by a transverse frame bar 4faud at their rear ends by a transverse frame bar 5, whereby a rigid frame structure is formed. At one side the frame is supported by a land wheel ii mounted on the crank end of a horizontal axle I juurnaled to rock in bearings 8-8 fixed to the Mains. it its opposite side the frame is su 'iporled by a furrow wheel mounted on the crank end of a horizontal axle 1t journaled to rock in bearings 1111 applied to the beams in advance of the axle 7 if; mounted on the axle T at the adjusting lever 12 dog 13 adapted to provided with a locking Specification of Letters Patent.

Serial No, 636,142.

engage the teeth of a seginen'v frame lfi'nxed to the side of the frame, by which means the lever may be held in its different positions of adjustment on the axle T as an axis. The lever is extended downwardly below the axle in the form of an arm 16 which is connected by a forwardly extending link 17 to an arm 18 fixed to the end of the axle 10, by which means the axle may be rocked to adjust the furrow wheel. Fixedly mounted on the axle 7 adjacent the lever 12 is a second adjusting lever provided with a locking dog 20 eiigaeii n the teeth of a segment frame 21, carried by the lever 12, the adjustment of this lever 15 serving to rock the axle T and to correspondingly adjust the land wheel rocked, the land wheel axle will be rocked with the'lever 19. and the furrow wheelaxle will be rocked by reason of the connection of the lever 12 with the furrow wheel axle through the medium of the arms 16 and 1.8 and their connecting link 17.

If it is desired to adjust the land wheel alone. and independently of the furrow wheel, the lever 19 is unlatched from the segment frame 21 and being moved, will rock axle 7, thereby adjusting the land wheel but not disturbing the lever 12, because the land wheel axle rotates loosely in the lever 12 and the latter remains locked to the fixed segment frame 1%.

If again it is desired to adjust the furrow wheel only and independently of the land wheel, then lever 19 is unlatched from the segment frame 21 of lever 12 and is fixedly held by the hand. Lever 12 is then unlatched from the fixed segment frame 14 and operated, with the result that the furrow wheel axle will be rocked by the link connection between the arms on the axle and lever 12, and when the proper adjustment has been Wheels may be adjusted in unison as desired.

I have illustrated in the accompanying drawings and described above the preferred Patented Nov. 9, 1915.

means for carrying my invention into efl'ect. It is manifest, however, that the details shown may be variouslychanged and modified within the knowledge of the skilled mechanic without departing from the spirit of my invention; and'it is to 'be understood that the invention is 'not 'limited to any particular form or construction of the parts except'in so far as such limitations are specified in the claim. v

Having thus described my invention, what I claim is i In a wheeled plow, the combination of a lever; a second arm depending from the lever and independent of said segment member and substantially parallel with the first-mentioned arm' link lying in a horizontal plane and connecting said arms and extending approximately at right angles to and constantly in a plane below both axles and whereby when the lever is actuated the furrow-wheel axle only is rocked; a segment-member mounted on the frame for locking the lever in difl'erent positions of adjustment on the frame; a secondary lever fast on the land-wheel axle for efiecting movement thereof independent of the-furrow-wheel axle; both of the levers being disposed in a plane corresponding tothe-point of attachment to the land wheel/axle of the lever fast thereon, and means on the secondary lever and engageable with the seg ment-member on the primary lever to lock the levers together, whereby movement of the primary lever to rock the furrow-wheel axle will actuate the secondarylever to rock the land-wheel axle simultaneously and thereby move the two wheelrcarrying crankarms in the same direction. In testimony whereofl 'aflix my signaturein presence of two witnesses.
